The Parable of the Wise and Foolish Virgins

Then shall the kingdom of heaven be likened unto ten virgins, who took their lamps, and went forth to meet the bridegroom. And five of them were foolish, and five were wise. For the foolish, when they took their lamps, took no oil with them: but the wise took oil in their vessels with their lamps. Now while the bridegroom tarried, they all slumbered and slept. But at midnight there is a cry, Behold, the bridegroom! Come ye forth to meet him. Then all those virgins arose, and trimmed their lamps. And the foolish said unto the wise, Give us of your oil; for our lamps are going out. But the wise answered, saying, Peradventure there will not be enough for us and you: go ye rather to them that sell, and buy for yourselves. And while they went away to buy, the bridegroom came; and they that were ready went in with him to the marriage feast: and the door was shut. Afterward came also the other virgins, saying, Lord, Lord, open to us. But he answered and said, Verily I say unto you, I know you not. Watch therefore, for ye know not the day nor the hour.
